Our story
The three of us met through Muay Thai — training together, cornering each other at competitions, and arguing about fight tactics long after the session ended. One of us is more than a fan: he coaches to this day at Sparta Muay Thai Gym in Bila Tserkva, Ukraine — one of the strongest gyms in the country, home to world and European champions and many champions of Ukraine, with years of competitions behind the team.
Watching that gym work from the inside showed us what clients never see: class rosters scattered across notebooks and messenger chats, attendance kept in someone's head, payments chased after the fact. And on the other side — people calling around town just to learn which gyms teach their sport, what a trial class costs, or whether the evening group has space. Nobody was doing their job badly; there simply was no tool built for how gyms, coaches, and their clients actually connect.
So we decided to build it ourselves. GymJoin is a platform where gyms and private coaches manage trainings, schedules, and admins in one place — and where anyone, from professional athletes to complete beginners, can search by city, filter by sport, compare gyms and coaches, subscribe, and check in without a single back-and-forth message.
Our mission is simple: make sport more possible and more comfortable for people on both sides of the ring. Less admin for gyms and coaches, more time for coaching — and for everyone else, finding the right gym, coach, or training should take no more effort than showing up and doing the work.
We're still training, still coaching, and still building — with in-app payments, private training scheduling, messaging, and more on the way. GymJoin is made by people who train, for people who train — and it all started in the gym where we met.
